Infinitives and Infinitive Phrases Worksheets

The Infinitives and Infinitive Phrases Worksheets are a structured and engaging set of grammar exercises designed to help students clearly understand and confidently use infinitives in written and spoken English. These activities guide learners from basic recognition of infinitives (to + base verb) to identifying complete infinitive phrases and understanding how they function within sentences.
Through a variety of tasks—such as identifying and circling infinitives, completing sentences, correcting errors, classifying infinitives as nouns, adjectives, or adverbs, and writing original sentences—students develop both accuracy and fluency. The exercises gradually increase in difficulty, reinforcing learning step by step while encouraging critical thinking and application in real-life contexts.
This worksheet set supports grammar mastery by strengthening sentence structure, improving clarity in writing, and building a solid foundation for more advanced language skills. It is ideal for classroom instruction, homework practice, review lessons, or assessment use in upper elementary and middle school settings.
